Machines serving for mechanically operating kitchen appliances andauxiliary devices, are known in the art. Kitchen machines designed fordriving a plurality of such appliances and devices are used only inrestaurants, hospitals and the like.

The small-size household kitchen machines on the market today ordinarilycomprise only one drive connection for alternatingly and alternativelyoperating the kitchen appliances and auxiliary devices. Mounting anddemounting the latter is of decided disadvantage and inconvenience tothe cook, since each one of them has to be fetched from and put backagain to its place.

Such disadvantage and inconvenience is avoided by my present invention,the subject matter of which is a house-hold kitchen machine incombination with a plurality of kitchen appliances and auxiliary devicessuch as mixers, kneaders, heaters, vegetable and meat cutters andcomminutors and the like, which devices are mounted on the machinewhether in use or not. Such machine comprises an electric motor, astationary drive gear, a rotatable stand whereon the said devices aremounted in circular arrangement, and a gear wheel for each of saiddevices, journaled in the said stand, the whole in such combination thatupon turning the said stand, any one of the said devices may be put intooperation.

Two embodiments of my present invention are shown in the accompanyingdrawings, in which l is an elevation, partly in section of one form ofthe invention,

Fig. 2 is a cross-section .on line II-II of Fig. 1, and

Figs. 3 and 4 are views, similar to Fig. 1, at right angles to eachother, of a modification.

In the embodiment shown in Figs. 1 and 2, the electric motor is mountedon top, and in that shown in Figs. 3 and 4 in the pedestal of themachine.

In the first embodiment, a mount 2 is secured to the stationary pedestalor column I, forming part thereof, and a motor-mounting cap 3 is securedthereto. A drive shaft 4, a jack shaft 5, and an intermediate-wheelshaft 6 are journaled in the mount 2. A stand or turret I, .on which aplurality of kitchen devices, e. g. five, are i mounted is pivoted onmount 2. In the drawing only one of the said kitchen devices, 1. e. acutter and comminutor 9, is shown. The driving elements, comprising fivespur gears 8, for the said devices 9 are journaled in the turret 1.

Anelectric'mot'or I0 drives a pinion I3. keyed to jack shaft-5, by wayof shaft a and the bevel gears II and I2. Pinion I3 meshes with theintermediate gear I4 keyed to intermediate shaft 6, and with one of thespur gears 8. The latter drive their appurtenant kitchen devices, butonly one at a time. By turning turret I, any one of the gears 8, i. e.any one of the devices 9, alternatively may be brought to mesh with gearI4.

Turret 1 is located by the click or detent I5 so as to bring about aproper engagement of the spur gears I4 and 8. To such end, a recess isprovided on the top plate of turret I for each operative settingthereof, 1. e. for each gear 8.

In order to prevent a jamming of gears I4 and 8 when rotating turret I,the latter is axially displaceable on mount 2. When one of the gears 8and the gear I4 mesh properly, a spring I6 brings turret 1 into abutmentagainst the shoulder I1 of mount 2, and the spring-loaded detent I5snaps into the corresponding recess on the top plate of turret I, thusensuring the proper interengagement of gears I4 and 8.

In the embodiment shown in Figs. 3 and 4, a pedestal or column 25, builtup of portions 20a, 26b, 29c and 26d, is set up vertically on a table. Aturret 2| is pivoted on portion 290, bearing on the shoulder 20cthereof.

A plurality in this case four kitchen devices 22 are mounted on studs2|a, of turret 2|, only one of the said devices being shown in thedrawing. A trough 22a cooperates with one or more of devices 22 forbeating or stirring operations.

The electric motor (not shown) is housed in the foot portion of pedestal2e, and its shaft 23 drives a jack shaft 23 by way of the spur gears 24,25. A Worm 27, secured to jack shaft 26, meshes with a worm wheel 28secured to an intermediate shaft 29. A spur gear 39 also is secured tothe latter and meshes with a pinion 3| secured to turret 2|. Fourpinions 3| are provided for i. e. one for each kitchen device mounted.Each of the latter is provided with a hollow-shaft 22b which is adaptedto be engaged by a pin 3|a integral with pinion 3|.

To ensure a proper interengagement of gear 30 and any one of the fourpinions 3| of turret 2| and to maintain such interengagement during theoperation of a device, a spring-1oaded detent 32 is provided in the topportion 20d of column 20, which detent is adapted to snap into any ofthe four recesses 32a. provided in the top face of turret 2|.

In order to prevent pinions 3| from jamming with the gear 30 of thedrive gear, turret 2| is axially displaceable, against the action of thespring 33, relative to cap 20d of column 20.

What I claim and desire to secure by Letters Patent is:

1. A turret type domestic kitchen-machine of the character described,comprising an electricmotor, a stationary pedestal column in which saidmotor is mounted, a gear system driven by said motor, a turret pivotedon said column, a spurgear forming part of said gear system driven bysaid motor and rotatable about an axis at right angles to the turningaxis of said turret, a plurality of independent pinions borne forrotation in said turret and adapted to be brought into mesh with saidspur-gear, a plurality of individual kitchen devices secured to saidturret and adapted to be operated by said motor-driven gear, one at atime, by Way of one of said pinions, and means to permit an axialdisplacement of said turret against spring-action automatically causedby any of said pinions riding on said spur gear into engagement with thelatter when said turret is turned.
